Given numbers are 663,471,984,785,771
The least common multiple of numbers can be find using the prime factorization method or LCM formula.
The LCM of 663,471,984,785,771 is 43872274680.
Find LCM of 663,471,984,785,771 with Prime Factorization
| 3 | 663, 471, 984, 785, 771 |
| 157 | 221, 157, 328, 785, 257 |
| 221, 1, 328, 5, 257 |
Multiply the prime numbers at the bottom and the left side.
3 x 157 x 221 x 1 x 328 x 5 x 257 = 43872274680
Therefore, the lowest common multiple of 663,471,984,785,771 is 43872274680.
LCM formula is LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
Firstly, we have to find the product of all the numbers.
663 x 471 x 984 x 785 x 771 = 185974572368520
Then, let us find the GCF of these five numbers. To do so, we have to list down the factors for each number and choose the highest factor that is in all of the lists.
663 : 1, 3, 13, 17, 39, 51, 221, 663
471 : 1, 3, 157, 471
984 : 1, 2, 3, 4, 6, 8, 12, 24, 41, 82, 123, 164, 246, 328, 492, 984
785 : 1, 5, 157, 785
771 : 1, 3, 257, 771
1 is the greatest number that appears in all the lists. Therefore, we can determine that the GCF of 663,471,984,785,771, is 1.
Now, the common factors can be found like this.
663:3x 13x 17
471:3x 157
984:2x 2x 2x 3x 41
785:5x 157
771:3x 257
From this, we can see that the common factors because they appear for more than two numbers. So, just multiply them all together.
3x 3x 3x 157 = 4239
Therefore, the value for common factors is 4239.
Now that we have all the elements of the formula, we can plug them in to calculate the LCM.
LCM(a1, a2, an) = (a1 x a2 x an)/{GCF(a1 x a2 x an) x common factors}
LCM = 185974572368520/(1x4239)
LCM = 185974572368520/4239
LCM = 43872274680
Thus, we can understand that the LCM of 663,471,984,785,771 is 43872274680.
